root cap

n. Botany

A thimble-shaped mass of cells that covers and protects the root tip.

root cap

a structure found at the apex of all ROOTS (except those of many water plants), produced by the APICAL MERISTEM. The cap consists of a thimble-shaped collection of PARENCHYMA cells which have a protective function. As the root pushes its way through the soil the outer (older) cells of the root cap are sloughed off and replaced by new cells from the MERISTEM.
